Customer wants BMW Apps in his MY2009 7-Series. BMW Apps is only available factory-installed from MY2011-on. A dealer-installed retrofit was just published in the OEM parts database a couple of months ago but again, only for MY2011-on 7-Series.

1) TCU-to-Combox install required coding of the iDrive CIC
2) Combox retrofit removes current BMW Assist account -Combox Telematics requires to be registered with Assist to transfer account to new SIM.
3) BMW Live option removes all Assist features from iDrive screen. Once Assist account is transferred then the Assist roof button will work to call Assist. But no Assist feature will be accessible thru the iDrive screen, including the BMW Remote app, and MyInfo (Google Send-To-Car). This is because BMW Live is not an USA feature.
